Product Introduction
Sodium Hexametaphosphate (SHMP) is a versatile dispersant and depressant widely used in mineral flotation. It selectively depresses gangue minerals such as carbonates (e.g., calcite, dolomite), silicates (e.g., quartz), and phosphates by forming stable complexes with Ca²⁺, Mg²⁺, and other metal ions on mineral surfaces . This action enhances the hydrophilicity of gangue particles, preventing their flotation and improving separation efficiency.
As a powerful dispersant, SHMP reduces slime coating and particle aggregation by increasing surface electronegativity and steric repulsion . This is critical in fine-grained ores (e.g., nickel, phosphate, or coal) where slimes hinder target mineral recovery . Applications include depressing quartz in lepidolite flotation , reducing ash in coal processing , and upgrading phosphate concentrates . Its cost-effectiveness and ability to elevate concentrate grade while lowering reagent consumption make it invaluable in modern mineral processing.
Product Advantage
Sodium hexametaphosphate (SHMP) serves as a highly effective depressant and dispersant in the flotation of various ores. Its key advantage lies in its selective inhibition of unwanted gangue minerals. For instance, in phosphate ore processing, SHMP competes with collectors on the surface of apatite, reducing collector adsorption and thereby depressing the floatability of phosphate minerals when needed . It also shows a strong depressing effect on carbonate minerals like calcite and silicates , which is crucial for separating valuable minerals from gangue. Furthermore, by altering mineral surface charges, SHMP enhances electrostatic repulsion between particles . This action helps reduce slime coating and prevents non-selective aggregation, leading to a cleaner separation and a higher-grade concentrate .
The strong dispersion capability of SHMP significantly improves overall flotation efficiency, especially in fine-grained or argillaceous ores. By increasing the electronegativity of particle surfaces, SHMP promotes particle repulsion , effectively minimizing mechanical carry-over of fine slimes into the froth product. This results in better selectivity and lower ash content in the final concentrate, as observed in coal flotation . Its dispersing power is also beneficial in complex ores like nickeliferous ones, where it mitigates the coating of serpentine slimes on valuable mineral surfaces . As a cost-effective and versatile reagent, SHMP contributes to optimized flotation conditions, improved recovery rates, and the production of higher-quality concentrates across various applications .
